HORACE oAvE VJEALFBESON, or LQNDQN, nsur n- LOCKING DEVICE .FOR BAGS ANDTHE LIKE.

T0;a ZZ whom it may concern Beiit lniown' that I, HOR'ACECAVELL J EAF-ransom, a subject of the King' of Great, Britain and Ireland, residingat'176 Pento'h}. I,

ville road, -Kings, Cross, London, N., Eng-1 land, have invented certainnew I and useful. Improvements in Locking Devices for Bags; and "thelike, of whichthe following isiia specification.

This invention relates to safety locking orsecuring devicesfor. bagslandthe" like of the kind in which a hinged ring loop or link is arranged tobe slippedover the usual'interr lockingspringknobs or balls of theclosing device in. order to V safeguard the latter against unintended oraccidental opening. due either to wear or to the bending of the" knobstems or to strain on or bending of the frame or other causes.

Now, according to this invention I secure to one of the locking membersa ring, link or catch adapted to be'turned over both knobswhenfhelatte'r are employed as a closing device automatically as thelatter is actuated during the closing operation.

In a'practical embodiment of my invention the stern carrying one of theknobs or balls is pierced below. the knob. and a split ring is threadedthrough the p'assage so provided, so as to be hinged therein.

Moreover, a lug or projection may be arranged on the bag-frame so thatthe ring will be caused to engage it as 1t is swung upward and over thetwo knobs or balls when the two frame parts of the bag are pressedtogether. This lug or projection may be arranged on the bent portion ofthe stem of the second knob, or that portion of the stem which issoldered or secured to the frame, or it may be a part of or on the bagframe.

The exact position where the ring, link or catch is secured to the knob,stem or bag frame will be determined by the size, height or position ofthe interengaging knobs or locking members.

To open the bag it is only necessary to throw back or disengage thecatch or ring and press the knobs apart, in the usual manner.

The ring itself may be in the form of a transversely orcircumferentially split ring, and while, preferably, of circular form itmay, in some cases, be of oval or other shape.

Specification of Letters Patent.

Application filed December 26 Seria1 No. 20 8,$ )1 8.-

In order that. the hole to be bored in the V stem (of th'ef'kn'ob. maybe as s 'an as, possible" so a's'not, tounduly weakenlit, I may employ.

a circumferentially split ring or double wire.

coil'having fonly a single 'thickness' at that portion fwhereuthe ringpasses through. the stem.

The. invention will now be described with reference to theaccompanying"drawings,

which illustrate an embodiment thereof.

Figure 1 shows the members, of a ba frame with the, usual. locking ballsopene and y a split ring arranged "according to this invention in it'sinoperative position. i Fig. 2 shows the bag frame closed but notlocked, and Fig.3 shows the ring in looking position and 'thebag frameslightly opened. Fig. 4 shows one form of projection to cause the ringto automatically lock whe the bag is closed.

F ig. I5 is a perspective view of a modified constructional form of. theinvention.

Fig. 6 a front view of thesame showing theparts during the closingaction." i

Figil'? is a closed, and.

F ig'. 8 is a' plan view of Fig. .7. I Referring. first to Figs. 1,2211,13, can represent the upper portions "of the two membersconstitutinga bag frame. 72,1)

are the interengaging knobs of well-known construction carried on stems0, 0 soldered or otherwise secured to the members a, a/ respectively.

Hinged or pivoted in or on one of the stems b is a split ring 03 ofstrong thin material, so that the stem is not seriously weakened by thehole 0 in which the ring is rotatably held. The ring is of such diameterthat when the knobs are in interlocking ngagement and the ring is swungover gently it is capable of clearing the knob 6, preferably with aslight frictional or Springy action, before dropping into the positionshown in Fig. 3, in which the bag mouth is locked thereby. To open thebag the ring must first be slipped off the. knob b, and then the twoknobs b, I) pressed apart in the usual manner.

The ring 03 conveniently consists of a double coil of thin spring wire,except at the part seated in the hole 0 when it is of single thickness,as shown in Fig. 1.

lateral view showing the, parts Fig. A, carries the ring d toward thelug or projection 0* so as to raise its free end and at the same time.to impede its further displacement for a moment in opposition to itsresiliency so that in the next instant, during which the knob Z2, afterpassing the knob b and snapping in front of it, (Fig. 2), with the usualquick forward jerk, due to the resiliency of the stems, the momentum ofinertia thus imparted to the ring coupled with the resiliency previouslystored therein causes the ring to fly over both knobs and to assume thesafe locking position.

In the constructional form shown in Figs. 5 to 8 the security member hasthe form of a loop cl which is actually hinged in a bore 6 in the knobb. To provide for the guidance of the loop during its oscillation aboutits hinge the knob 12 is laterally cut away on each side as shown at 6and an offset or abutment b is maintained to limit this movement inupward direction. The function of the projection 0* is here actuallyperformed by the knob 71' which, as it approaches the knob I) (Fig. 6)during the closing of the bag, strikes the loop (Z so as to cause thelatter first to swing up into the position shown in dotted lines inFigs. 6 and 7 against the abutment b and from this position to dropautomatically over the Copies of this patent may be obtained for knob bimpelled by the sudden jerk as the knobssnap one behind the other andaided by gravity in this action.

What I claim and desire to secure by Letters Patent is 1. A lockingdevice for bags and the like comprising in combination with a closingdevice, such as knobs adapted to engage one with the other when in theclosing position of a ring, catch arranged on one of the members oronthe bag frame so as to be thrown into engagement w1th and to secure theclosing device in its closed position'automatically by the closingaction of the latter.

2.- A locking device for bagsand the like as set forth in claim 1,having means adapted to assist or to guide the locking deviceautomatically to engage the closing device during the closing of thelatter.

3. A locking device for bags and the like as set forth in claims 1 and 2in which the locking member is in the form of a ring of spring wirefreely pivoted or hinged and adapted tocooperate with a guide during theclosin action of the bag so as to fly over and to embrace the closingdevice.

4;. A locking device for bags and the like as set forth in claim 1 inwhich the loop is hinged in one of the knobs and the latter five centseach, by addressing the Commissioner of Patents Washington, D. G.
